Computes contour polygons by applying marching


This module computes contour polygons by applying marching squares to a rectangular array of numeric values.

Contour polygons are GeoJSON, you can transform and display them using standard tools. Contour plots can also visualize continuous functions by sampling.

Contours can also show the estimated density of point clouds, which is especially useful to avoid overplotting in large datasets. This library implements fast two-dimensional kernel density estimation.

Node.js is an event-based server-side JavaScript engine.
